mb/google/nissa/var/quandiso: Tune P-sensors for Linux 5.15 sx9324
driver
Since DRIVERS_I2C_SX9324_SUPPORT_LEGACY_LINUX_DRIVER value on dedede
cannot meet DRIVERS_I2C_SX9324 on nissa, need to update the tuning
value. Update proximity sensor fine tune value with quandiso EVT
machine.
BUG=b:314550601
BRANCH=firmware-nissa-15217.B
TEST=emerge-nissa coreboot and verify p-sensor
watch 'cat /sys/bus/iio/devices/iio:device*/*raw'
